The Geological Survey of India has warned that a planned tunnel in Bangalore’s Hebbal area could damage a 3‑billion‑year‑old rock formation at Lalbagh Botanical Garden.
The Geological Survey of India (GSI) has issued a warning that a proposed tunnel project in Bangalore’s Hebbal locality may jeopardise a 3‑billion‑year‑old rock formation at Lalbagh Botanical Garden.
The GSI’s statement, released earlier this week, highlights the geological significance of the rock and the potential impact of underground construction on its integrity.
Bangalore authorities have not yet confirmed whether the tunnel will proceed, but the GSI’s alert underscores the need for careful assessment of heritage sites before infrastructure development.
The Lalbagh rock, part of the city’s ancient geological history, is a key feature of the botanical garden and a point of interest for scientists and visitors alike.
Stakeholders are now calling for a thorough environmental and geological review to protect the site from possible damage.
